WavPack is a completely open audio compression format providing lossless,
high-quality lossy, and a unique hybrid compression mode. Although the
technology is loosely based on previous versions of WavPack, the new version
4 format has been designed from the ground up to offer unparalleled
performance and functionality.
In the default lossless mode WavPack acts just like a WinZip compressor for
audio files. However, unlike MP3 or WMA encoding which can affect the sound
quality, not a single bit of the original information is lost, so there's no
chance of degradation. This makes lossless mode ideal for archiving audio
material or any other situation where quality is paramount. The compression
ratio depends on the source material, but generally is between 30% and 70%
(generally lower for typical popular music and somewhat better for classical
music and other sources with greater dynamic range).
The hybrid mode provides all the advantages of lossless compression with an
additional bonus. Instead of creating a single file, this mode creates both
a relatively small, high-quality lossy file that can be used all by itself,
and a "correction" file that (when combined with the lossy file) provides
full lossless restoration. For some users this means never having to choose
between lossless and lossy compression!

By default libtool replaces -export-symbols <file> with -retain-symbols-file
<file> on ELF systems, but this doesn't really do what -export-symbols is
meant to do. On GNU ELF systems it converts <file> to a simple version
script first and then uses -version-script instead of -retain-symbols-file.
Let USES=libtool patch libtool scripts to do this on all systems with GNU
ld(1).
Bump PORTREVISION on all ports where the build log contains -export-symbols.
audio/calf: This port builds a module that now exports only one function,
but it also builds a number of executables that link to this module and
expect to see other functions. Because it's already a bit dodgy to link to
a module (libtool warns about this) let the module continue to export only
one function and instead build an ordinary library from the same source that
the executables can link to. Fix a number of other issues in the same

Replace USES=libtool:oldver with USES=libtool or USES=libtool:keepla in
the 32 ports that still use it. Bump PORTREVISION on their dependent
ports except the ones that depend on these:
audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt
In these cases the same trick as in the recent gettext update is used.

Mass-conversion to the USE_AUTOTOOLS New World Order. The code present
in bsd.autotools.mk essentially makes this a no-op given that all the
old variables set a USE_AUTOTOOLS_COMPAT variable, which is parsed in
exactly the same way as USE_AUTOTOOLS itself.
Moreover, USE_AUTOTOOLS has already been extensively tested by the GNOME
team -- all GNOME 2.12.x ports use it.
Preliminary documentation can be found at:

which is in the process of being SGMLized before introduction into the
Porters Handbook.

Add wavpack.
Wavepack is a completely open audio compression format providing lossless,
high-quality lossy, and a unique hybrid compression mode.
In the default lossless mode no original information is lost, so there is no
change of degradation. Compression in this mode is between 30% an 70%.
